Question 1

What is the primary purpose of the REACH regulation in the context of PCB design?

Accepted Answer

Controlling registration and evaluation of chemical substances

Answer

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) requires manufacturers to identify and manage risks from chemicals used in products including PCBs.

Question 2

A PCB design engineer adds copper fill to reduce impedance and minimize EMI. Which FCC test limit category applies to a device sold commercially in the US for home use?

Accepted Answer

Class B (residential)

Answer

FCC Part 15 Class B limits apply to devices marketed for residential use and are stricter than Class A industrial limits.

Question 3

Under IPC Class 3 requirements, what must be done to conformal coating voids discovered during inspection?

Accepted Answer

They are rejectable defects requiring rework

Answer

IPC-A-610 Class 3 treats coating voids over exposed circuitry as rejectable conditions that require rework to ensure reliability.

Question 4

Which marking must appear on a product sold in the European Economic Area to declare conformity with applicable EU directives?

Accepted Answer

CE mark

Answer

The CE mark (Conformité Européenne) is a mandatory conformity marking indicating a product meets EU health, safety, and environmental requirements.

Question 5

IPC-2152 provides guidelines for which critical PCB design parameter?

Accepted Answer
